I can't quite understand why one would bother to do this?

The 30 minute test consumed 400 litres of domestic kerosene.

Still, I'm glad they are not my neighbours.

The challenge?

Impressive achievement I'd say, I'd would not know how to rebuild a lawn mower engine!

You never know when the question 'How many litres of domestic kerosene would an RB211-22B consume in a 30 minute test run ?' will crop up in a pub quiz !!

Ooh, sounds like they've lost a sheep in there or sumat. Bit of a rattle...?

In can quite understand getting say, an old railway engine working and actually moving along a line (as Marks DTM has done), but an engine on its own without the rest of the plane seems a bit pointless...and rather dangerous, too.

Sheep don't rattle, they moan.....seductively.

I wouldn't know, don't think I've ever met a sheep.

Only to anything in front of it.. or behind it.. or to the sides of it..

Plenty of people would consider rebuilding an old railway engine in order to chug up and down a non-'working' tourist line equally silly

Because we still can do stuff like this, eccentricity at it's best

Another couple of thousand litres to get it properly hot and it'd have smoothed out nicely.

Great British eccentricity at its best and I'm sure it has some uses.

Maybe Michael2.6 would like to borrow it, to run at full blast for the short time it would be tethered to their neighbours extension.

[Nickbat]

Of course it's pleasingly eccentric, but my point is that it doesn't actually DO anything, other than behave as it did for many years and was, indeed designed to behave, i.e as a jet. Now if they engineered this into a jet-powered machine - for example a jet-powered snow clearer mounted on lorry for use on motorways in the winter THAT would be both eccentric...and potentially ever so slightly [but probably not] useful.

Quite a small engine by todays standards but when the first one was being assembled at Barnoldswick no one could believe the size of it. (think it was 9 foot diameter)
The fan blades have quite a bit of clearance between them and clatter about due to gravity when spinning slowly. At working rpm however they bend forward and each blade locks onto the next one forming a rigid disk.
I have a piece of an early blade root forging, passed down from my dad. It is some form of titanium alloy, been used as a dolly, an anvil and all sorts over the years and is still polished and doesnt have a mark on it, files wont touch it.

when I win the euromillions I reckon I might invest in one of those as a space heater and for blasting the dust out the workshop.
